1. A train takes 1.5 hours at a constant speed of 65 mph to arrive at the destination. How many miles did the train travel?

• A. 97.5 miles
• B. 100 miles
• C. 98 miles
• D. 95 miles

Correct answer: A

Rationale: To calculate the distance traveled, multiply the speed by the time taken: 65 mph × 1.5 hours = 97.5 miles. Therefore, the correct answer is A. Choice B (100 miles) is incorrect as it results from rounding up, which is not necessary. Choice C (98 miles) and Choice D (95 miles) are incorrect as they do not reflect the correct calculation based on the given speed and time.

2. What does the mass of one mole of a substance represent?

• A. Atomic mass
• B. Mass number
• C. Molecular weight
• D. Molar mass

Correct answer: D

Rationale: The mass of one mole of a substance is represented by its molar mass. Molar mass is the mass of one mole of a substance and is expressed in grams per mole. It is calculated by summing the atomic masses of all atoms in a molecule. Therefore, the correct answer is D - 'Molar mass'. Choice A, 'Atomic mass', refers to the average mass of an atom of an element. Choice B, 'Mass number', is the total number of protons and neutrons in an atom's nucleus. Choice C, 'Molecular weight', is the average mass of a molecule relative to 1/12 of the mass of an atom of carbon-12.

3. Which of the following should never be performed by a healthcare professional?

• A. Heimlich maneuver
• B. Euthanasia
• C. Assessment
• D. Palliative care

Correct answer: B

Rationale: Euthanasia, which involves deliberately ending a person's life to relieve suffering, is a controversial and illegal practice in many countries. Healthcare professionals should not be involved in performing euthanasia as it goes against medical ethics and principles of preserving life and providing care. Assistance in hastening death is not within the scope of healthcare professionals' responsibilities. Assessments, such as physical examinations or patient evaluations, are crucial for diagnosing and treating patients. Palliative care focuses on improving the quality of life for individuals with serious illnesses and should be provided by healthcare professionals. However, euthanasia is not an acceptable practice for healthcare professionals due to ethical considerations and legal restrictions.

4. What is the main function of the nervous system?

• A. Transporting blood
• B. Protecting the body from infection
• C. Regulating body temperature
• D. Digesting food

Correct answer: C

Rationale: The main function of the nervous system is to control and coordinate body activities by transmitting signals between different parts of the body and responding to internal and external stimuli. This allows for the regulation of body temperature, movement, sensory perception, and various other functions necessary for homeostasis. Choices A, B, and D are incorrect as they do not align with the primary role of the nervous system. Transporting blood is mainly carried out by the circulatory system, protecting the body from infection is a function of the immune system, and digesting food is the role of the digestive system.

5. Which is not listed as an example of a low-impact sport?

• A. Martial arts
• B. Basketball
• C. Yoga
• D. Weight lifting

Correct answer: B

Rationale: Basketball is not listed as a low-impact sport in the extract provided; the others (martial arts, yoga, and weight lifting) are considered low-impact activities. The extract mentions that students can participate in low-impact sports like yoga, martial arts, and weight lifting in modern PE classes, emphasizing their benefits and the focus on general skills. Basketball, on the other hand, is not included in the list of low-impact sports mentioned in the extract, making it the correct answer. This demonstrates the importance of understanding the difference between high-impact and low-impact sports for maintaining fitness and health.
